JOHN TIEBOUT, OF BROOKLYN, NENV YORK, ASSIGNOR TO HIMSELF AND WM.TIEBOUT, OF SAME PLAGE.

BUNG- CUTTER.

Specification of Letters Patent No. 28,640, dated June 5, 1860.

To all lwhom 'it may concern.

Be it known that I, JOHN TIEBOUT, of the city of Brooklyn, in the countyof Kings and State of New York, have invented a new and Improved Devicefor Cutting Bungs, &c.; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawing, forming a part of this specificat-ion, inwhich- Figure l represents a sectional front elevation of my invention.Fig. 2 is a horizontal section of the same, the line :0, Fig. l,indicating the plane of section.

Similar letters in both views refer to corresponding parts.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation with reference to thedrawing.

The driving shaft O, has a longitudinal sliding motion in the frame Abeing guided by the cross-bar B and by a tubular projection D which issecured to the lower crossbar. A rotary motion is imparted to the shaftO by means of a pulley E which is of sufiicient length to allow ofsliding the shaft up and down without throwing off the belt.

Secured to the lower end of the shaft C, is a disk F by means of a screwor screws a or in any other convenient manner. This disk is furnishedwith a series of radial slots b, the number of which corresponds to thenumber of the cutters to be employed and which form the guides for theadjustable hinges c to which the cutters G are attached by means ofpivots (Z. These hinges are secured to the disk by means of screws e orin any other convenient manner so that they can be moved nearer to orfarther from the center of the shaft as may be desired. The

cutters are secured to arms 7, the upper ends of which are bent from thecenter of the shaft C as clearly shown in Fig. l, and these arms passthrough another disk H similar move up and down.

to the disk F. This second disk however is not connected to the shaft Obut it is retained by a neck g in the lower end of the tubularprojection D in such a manner that it rota-tes freely without beingallowed to Adjustable guide plates 7L are secured to the under side ofthe disk H, which is furnished with radial slots L to allow said guideplates to be moved nearer to or farther from the center, and they (theguide plates) are provided with openings just large enough to admit thearms f of the cutters.

The operation is as follows: The hinges o and the guide plates L areadjusted according to the size of the bungs or corks to be cut, and thelength of the cutter arms f is such that when the shaft O is up andbefore it begins to move down the bent portion of the same extendsbeyond the upper disk H. As soon as the shaft begins to be depressed thebent portion of the cutter' arms enters the guide plates h and thepoints of the cutters are forced farther and fart-her apart, as thecutting proceeds.

By these means the bungs or corks are cut out to the desired bevel in asimple and effective manner, and all the parts of my device are soarranged, that they are not subjected to any liability to get out oforder and thereby to cause an interruption of the cutting operation.

lllhat I claim as new and desire to secure by Letters Patent isl. Thecombination with the disk F, and arms f, of the adjustable hinges 0, asand for the purpose herein shown and described.

2. The combination of the tubular projection D, guide plates it, andadjustable with the sliding shaft O, and disk F, as and for the purposeherein shown and described.

JOHN TIEBOUT.
